Abstract
Example embodiments for reducing thermal load in one or more exhaust gas lines are provided. One embodiment includes an internal combustion engine with liquid cooling, comprising at least one exhaust gas line, at least one coolant jacket, and a common boundary wall separating the at least one exhaust gas line and the at least one coolant jacket, wherein the common boundary wall includes a surface structure provided on sides of the coolant jacket in at least one locally limited region. In this way, the surface structure on the sides of the coolant jacket may increase heat transfer to reduce thermal loading.
